Which benefit is linked to using polymers in asphalt?

Using polymers in asphalt significantly enhances the material's performance properties. The incorporation of polymers contributes to improved tensile strength, which means the asphalt is better able to resist stretching and deformation under load. This strength is critical in preventing cracking, especially in the presence of environmental stressors such as temperature fluctuations and traffic loads.

The use of polymers allows the asphalt to maintain flexibility while also enhancing its overall durability. This flexibility is essential because it enables the asphalt to adapt to temperature changes, reducing the chances of cracking that can lead to pavement failures. Therefore, the benefit of improved tensile strength and resistance to cracking is a key advantage of polymer-modified asphalt, making it suitable for high-performance applications.

While other options suggest negative aspects, such as increased brittleness, decreased workability, and higher production costs, these characteristics do not align with the primary benefits associated with polymer usage in asphalt formulations. Thus, the focus on enhanced tensile strength and reduced cracking risk captures the essential value of integrating polymers into the asphalt mix.
